13.22. Set Up: The density of seawater is The area of the eardrum is with The pressure increase with depth is and Solve: 13.23. Set Up: where is the pressure at the surface of a liquid and is the pressure at a depth h below the surface. Solve: (a) For the oil layer, and is the pressure at the oil-water interface. (b) For the water layer, Reflect: The gauge pressure at the bottom of the barrel is due to the combined effects of the oil layer and water layer. The pressure at the bottom of the oil layer is the pressure at the top of the water layer 13.24. Set Up: The pressure change with depth is The arm is above the heart, so the pressure in the arm is less than the pressure at the heart. Solve: (a) maximum minimum (b) The pressure in the arm is less by an amount The blood pressure reading should be 13.25. Set Up: The pressure change with depth is The arm is above the heart, so the pressure in the arm is less than the pressure at the heart. On the moon, Solve: The pressure in the arm is less by an amount
